BOILER-CLEANER.

Specification of Izetters Patent.

Patented Sept: 1, 1914.

To all whom it may concern:

Be it known that I, NoRBnR'r SCHREIBER, a citizen of Germany, residing at Lincoln, in the county'of Logan and State of Illinois, have invented certain new and useful Improvements in Boiler-Cleaners, of which the following is a specification.

This invention relates to improvements in automatic boiler cleaners; and itsobject is to provide a device of this class that is applicable to any steam boiler, and that will automatically remove any scum or foam or other impurities from the surface of the water, within the boiler, before the same may have a chance to harden and form a scale; and with the foregoing and other objects in View, the invention consists in the combination and arrangement of parts to be hereinafter fully described in the following specification, pointed out in the claims and illustrated in the accompanying drawings which form a part of the specification, and in which Figure 1 illustrates a section of a stea boiler showing the application of my automatic cleaner, and Fig. 2 is a horizontal section on line 2-2 of Fig. 1.

Like reference characters indicate corresponding parts throughout the several views.

As thus illustrated 1 indicates the boiler and 2 the surface of the water within the same. ,Through a suitable opening in the,

boiler a tap 3 is inserted that may be provided upon its exterior portion with a suitable faucet or other regulating means 4:. To the interior end of the tap a flexible tube 5 is secured to the opposite termination of which a spider 6 is secured that is provided with a plurality of tube-arms 7 each of which registers with a circular intake pipe 8 provided with a plurality of apertures 9 through which the scum or other impurities upon the surface of the water may enter and so'be drained off through the arms 7, spider 6, flexible tube 5 and the tap. The upper end of the spider is provided with an extension 10 that connects it with a float 11 the buoyancy of which keeps the intake slots 9 at the surface of the water at all times.

The pipe 5 may be of any suitable length, depending upon the size and character of the boiler. In any event, however, this pipe 5 has suflicient flexibility to permit the float 11 and ring 8 to remain horizontal when the water rises and falls, and regardless of manner.

the position of the boiler. The horizontal slots 9 must remain exactly horizontal, and approximately at the surface of the water, if the apparatus is to work in the required Some boilers, such as locomotive, traction and marine boilers, are subject to changes of position during use, and with my invention the intakes 9 are always in operative position, even when the boiler rocks around, and also when the water rises and falls.

I do not limit myself to any particular construction, as the float, etc., may be of any suitable form, and the pipe 55 may be of any suitable character, without departing from the spirit of my invention.

What is claimed is 1. A boiler blow-off and cleaner comprising a float having an intake at the surface of the Water, and an outlet connection for said float, serving to maintain said float in horizontal position at the surface of the water, during the ordinary rise and fall of the water, and for all positions of the boiler.

2. A boiler blow-off and cleaner compris-. ing a float having an intake at the surface of the water, and an outlet connection for said float, serving to maintain said float in horizontal position at the surface of the water, during the ordinary rise and fall of the water, and for all positions .of the boiler, said connection comprising a pipe which is flexible to permit movement of said float in any direction.

3. A boiler blow-oflt and cleaner comprising a float having an intake at the surface of the water, and an outlet connection for said float, serving to maintain said float in horizontal position at the surface of the water, during the ordinary rise and fall of the water, said connection permitting bodily up and down movement of said float.

4:. A boiler blow-off and cleaner comprising a float having an intake at the surface of the water, and an outlet connection for said float, serving to maintain said float in horizontal position at the surface of the water, during the ordinary rise and fall of the water, and for different positions of the boiler, said connection being adapted to permit rocking and bodily movement of. said float in any direction.

5. A boiler blow-off and cleaner for re- 7 moving the scum from the surface of the water, comprlsmg a float, means having a horizontal slot forming a surface intake, supported by said float, and an offtake for said means, having provisions serving to enable said means to avoid tilting and thereby maintain said slot exactly horizontal at all times during the ordinary rise and fall of the water.

'6lA'boiler blov'v-ofl' and cleaner for removing the scum from the surface of the water, comprisin a float, means having a horizontal slot orming a surface intake, sup orted by said float, and an ofl'take for said means, having provisions serving to enable said means to avoid tilting and thereb maintain said slot exactly horizontal at all times during the ordinary rise and fall of the Water, and when the position of the boiler is changed.

, "LA boiler" blow-ofl and cleaner for reu ported by said float, and an 'ofltake for l-movement of said float in i-tive to the boiler, as downmotion thereof. as

moving the scum from the surface of the water, comprisin a float, means having a horizontal slot forming a surface intake,

said means, having provisions serving to enable said means to avoid tilting and thereby maintain said slot exactly horizontal at all times during the ordinary rise and fall of thewater, and whereby said float moves I bodily up and down.-

' 8. A boiler blow-ofl and cleanerfor removing-the scum from the surface of the water, comprisin a float, means having a horizontal slot orming a surface intake,

supported by said float, and an ofltake for said means, having provisions serving to enable said means to avoid tilting and therei-by maintain said slot exactly horizontal at all times during the ordinary rise and fall of the water, said ofi'take comprising a pipe which is flexible to permit movement of said 10. A boiler cleaner comprising an intake 1 havinga mouth for receivin the scum from the surface of the water, a oat movable up and down bodily, without tilting in any direction, during the ordinary rise and fall of 'thewater, joined to said intake for maintaming the operative position of said mouth atthe s'urfaceof the water, and an oiftake for discharging the scum,adapted .not to interfere with said bodily movement of the float.

11. A boiler cleaner comprising an intake having a mouth for receiving the scum from the surface of the Water, a float movable up and down bodily, without tilting in any direction, during the ordinary rise and fall of the water, joined to said intake for maintaining the operative position of said mouth at the surface of the water, and an ofltake for discharging the scum; adapted not to interfere with said bodily movement of the float, permitting tilting of the boiler in any direction without disturbing the operative position of said mouth.

12. A boiler cleaner provided with an in take having a horizontal inlet slot, and means for automatically maintaining said slot in operative position, horizontally, at the surface of the water, during the ordinary rise and fall thereof, thereby preventing the rise and fall of the intake from causing an variation of said slot from the horizontal.
